Background The chemical composition of aerosol particles provides key insights into the study of the behavior of planetary atmospheres. Measuring aerosol composition typically involves separating the aerosols from the carrier atmospheric gases, which can be challenging. Current methods for aerosol mass spectrometry (AMS) are well-established in the...

Eccrine sweat is an attractive biofluid for analyte detection and non-invasive health monitoring as it contains many biomarkers relevant to physiological health. Monitoring of electrolytes, metabolites, hormones, proteins and other exogenous agents in sweat may offer time-dynamic insights into metabolomic processes for health, nutrition and wellness....
